Description

The invention relates to devices for automating stamping production and can be used to clean parts from a strip or ribbon during stamping.

Closest to the proposed technical essence and the achieved affect is an automatic device for cleaning strips, comprising a housing and spring-loaded sliding pads installed therein with gaskets l.

A disadvantage of the known device is that, due to the constant pressing of the pads against the surface of the material being cleaned, there is an additional resistance to the advancement of the strip, and rolling it with dirt in the cleaning zone reduces the reliability of the device.

The aim of the invention is to improve the reliability of the device and improve the quality of cleaning.

This goal is achieved by the fact that in a device that is moved to a processing machine, in particular a press, comprising a housing and spring loaded sliding pads with gaskets installed in it, the pads are mounted rotatably in the plane of movement of the tape or strip and are provided with a rotation mechanism connecting the pads to the moving part of the press.

The rotation mechanism is made in the form of a shaft located in the housing and the carrier pad, a pair of bevel gears, one of which is fixed to the shaft, and a gear train, the rail of which has the ability to interact with the movable part of the press.

In addition, the device is provided with stops fixed on the housing between the pads, on the inner surface of the pads are made symmetrically located relative to the plane of the material supply grooves of variable depth and the device is equipped with a spacer element, for example a ball placed in the groove with the ability to interact with the stops

in fig. 1 shows the device, general view, section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - pads in the working position, section B-B in FIG. 3; in fig. 5 - the same, in the open position.

The device contains Ko | 5pus 1,

pads 2 and 3 with rivets attached 4 felt pads 5.

Kolo; | si 2. and 3 are interconnected

axis b i and mounted on the shaft 7

the possibility of axial movement on the shaft 7 and the axis b, the springs 8 and 9 of the pads are mounted on the axis 6 and the shaft 7. A screw 10 mounted on the end of the axis 6 serves to adjust the pressing force of the pads 2 and 3 to the strip 11.

On the inner surface of the pads 2 and 3, on the side of the strip 11 to be cleaned, symmetrically arranged grooves B are made, which terminate in slots C and D. In the groove B, a ball 12 is mounted so as to move along them. The depth of the nests C and D is chosen so that when you install the ball 12 in the nobility D pads 2 and

5 3 are pressed to the - cleaned strip 11, and when the ball 12 is installed in the socket C, the pads 2 and 3 are pressed from the strip 11, the shaft 7 is mounted in bearings 13 and 14 ° and is kinematically connected with

Q slider 15 presses by means of gears 16-18, shaft 19 and toothed rack 20 mounted on slider 15. Supports 21 and 22 are rigidly fixed to housing 1. To collect dirt, use container 23..

The device works as follows.

When moving, the slider 15 down (Fig. 1) starts turning the pads 2 and 3 clockwise (Fig. 2) and cleaning the surface of the strip 11. During the period of time the slider 15 moves from one extreme position to the other, shaft 7 with pads 2 and 3 rotates 90 °.

5 Marik 12, which is at the beginning of the rotation of the pads 2 and 3 in the socket D, reaches the stop 22 and with further rotation of the pads 2 and 3 moves along the grooves B to the socket C. At this moment

0, pads 2 and 3 open, and lane 11 is released from their pressure.

When the slider 15 moves in the opposite direction, the strip 11 begins to be fed, and the shaft 7, with the open pads 2 and 3, rotates counterclockwise (fig. 2).

The ball 12 by the stop 21 moves to the socket D, the boats 2 and 3 are closed at the upper position of the slide 15.

In the following, the process is repeated. The filling of the device with the strip 11 is carried out with the open pads 2 and 3.

5 The use of the proposed device in comparison with the known provides better cleaning of the material fed to the press, which leads to a prolongation

0 service tool. The device works stably when cleaning both m g (Who and thin material).
